INTERSERVE - DOOSAN JV WINS £46 MILLION NORTHUMBRIAN WATER CONTRACT

Interserve, the international support services and construction group, in joint venture with Doosan Enpure, has been awarded a £46 million contract by Northumbrian Water to upgrade the Horsley water treatment works in the Tyne Valley.

The 30-month project will see Interserve and process engineering firm Doosan Enpure build new treatment facilities alongside the current plant, which will continue to operate until the new project is complete. The site supplies up to 150 million litres of water a day to 800,000 customers on Tyneside.

The upgrade of the Horsley water treatment works, which was built in the 1970s and is nearing the end of its design life, will begin later this month. Services to local residents will not be affected while this work is carried out.

Adrian Ringrose, chief executive of Interserve, said:

"Both Interserve and Doosan Enpure have an established track record of delivering major utilities projects and we're excited to be working together on this project for Northumbrian Water which will give the residents of Tyneside a world-class facility that will be used for years to come. Where possible, we will use local resources, while supporting the local economy and employment in the region."

Noel Cooper, Northumbrian Water's head of water supply, said:

"We are committed to providing our customers with unrivalled customer experience. We know how much our customers rely on their tap water so ensuring it is excellent quality is a top priority. This work will not only ensure that the Horsley water treatment works continues to meet ever increasing water quality standards, it will also improve the site's resilience."

Untreated water for the Horsley works comes from the River Tyne at Ovingham and the Whittle Dene complex of reservoirs. The treated water supply from Horsley, which also serves the village of Horsley, together with additional water from the treatment works at Whittle Dene supplies the drinking water for Tyneside.
